<p>A ceiling fan blade attachment for enhancing the efficiency of conventional planar ceiling fan blades. A deflection element of the fan blade attachment may improve, add to, and/or replace the functional surface area of a conventional fan blade. The deflection element of the fan blade attachment comprises a positive twist spanning from the proximal end of the ceiling fan blade to either at least the approximate midpoint of the ceiling fan blade or the distal end of the ceiling fan blade. Preferably, the pitch of the fan blade attachment at its proximal end may be between 20 degrees to 35 degrees relative to a horizontal plane and the pitch of the fan blade attachment at its distal end may be between 5 degrees and 16 degrees relative to the horizontal plane. At least one fixation member may provide for securing the deflection element to the ceiling fan blade.</p> |
